- Repair loose connections. It’s important to make sure duct sections are screwed together so they don’t come apart as the unit expands or shifts. Additionally, you should make sure grills are fastened so air leaks can’t form between the wall and duct.
- Seal seams and joints with mastic. Also known as metal tape, mastic is effective for sealing duct seams and joints. On the contrary, regular duct tape can degrade based on weather conditions.
- Repair or replace flex ducts. The installation process can result in crushed ducts and lead to problems with your system’s airflow. When in doubt, replace bent ducts to maintain proper AC function.
- Insulate ducts properly. Do your ducts run through parts of the house that aren’t climate controlled? If you have ducts in the attic or basement, be sure to insulate them to prevent loss of heat or cold. For best results, use a vapor barrier to stop condensation from forming and affecting the insulation’s efficacy. Most experts recommend insulation that carries an R-value of six or higher.
Few of us are aware of all the factors affecting Tampa air conditioning function. And while many AC problems can and should be left to the professionals, homeowners should take the time to educate themselves about some of the elements impacting unit performance. Duct sealing and insulation are two factors that are critical to your air conditioning system’s energy efficiency. Here are some factors to consider when increasing your ductwork efficiency:
